VALVE-OPERATING MECHANISM.

i Specification of Letters Patent. Patented Jan, 27, 1920 Application led November 22, 1918. Serial No. 263,694.

To all whom t may concern Be it known that I, VILLIAM O. RENKIN, a. citizen of the United States of America, residing at Oradell, county of Bergen, State of New Jersey, have invented certain new and useful Improvements in Valve-Operating lwechanism, of which the folowing is a specification.

= at that particular station My invention relates generally to the semi-automatic operation of valves for controlling the `flow of fluid masses and more specifically comprises a modification and simplification of the apparatus shown and described in my UQS. 'Letters Patent No. 1,301,167, dated April 22', 1919.

The best form of apparatus at present known to me as embodying my present invention is illustrated in the accompanying two sheets of drawings in which;

Figure 1 isa partiallydiagrammatic view of. a sending station and multiple branch conduit Vand valves with my invention applied thereto, parts being. shown in section and others broken away.

Fig. 2 is an enlarged detail of one of the valves and'operating mechanism, and

Fig. 3 is a side elevation ofFig. 2.

Throughout the drawings like reference characters indicate like parts. p

In the general system to which my invention is usually applied there is ablowing tank 1, from which graduated quantities oli -material are discharged by. the use ofrcompressed air, as in the manner set forth in the pending application of Harry Arthur Kimber, Serial No. 214,755, Afiled January 31, 1918. The pulverized coal or other material so discharged from the supply tank 1, passes out through the main line conduit 5, to various branch storage bins.

In systems of the general construction above described.v as heretofore operated, each operator at a branch or local station has been required to keep track of his local fuel supply and, when the same approached eX- haustion telephone into the supply station operator stating the amount of additional fuel required. The supply station Operator when ready to deliver the amount required would telephone back to the local operator to set his switch valve 11, or 111, as the case might be, in the position which would close the main line conduit at that point and open the branch connection 1:2 or 112 to the local storage bin.

The supply station operator would thereafter send the required amount of fuel 'through the main line'ot the system to the local bin in question and, when the supply had been delivered, telephone the local operator to close his switch valve and reopen the main line connection'.

My present invention overcomes the dela)v and general awkwardness ot the procedure above described by making the action of the switch valves semi-automatic and controlablc by the supply operator at the suppl)v station through some such combinations of elements as are herein described.

On the axis' of each switch valve, as 11, is 'mounted a three armed lever 123, 113 or 213. The valves 11, 111, etc., are rotary twoway valves preferably of' the construction shown and described in my pending application Seria-l No. 211,750, filed January 31, 1918. To the oppositely extending arms ot each valve lever are connected pull-cords or chains, 15 and 28, or 115, 12S, etc., liv which the valve may be manually operated so as to rotate it into the position opening the line conduit and closing the branch (see valve 111) or in the other position which closes the line and opens the branch- (sec valves 11 and Q11). To the third and intermediate lever arm is connected a tension device. such as coiled spring 27, 127 or 22T. the other end of which is anchored to a fixed .support such as the arm 6, 106 or Q00. clamped to conduit 5, at the proper point to give the spring a tension sulhcient to turn the valve when free, into open-line and closed-branch position. lhenever the line is to be closed at an vv branch and the branch conduit. as 11, opened to fill the adjacent bin` the operator must pull on chain 28, 128 or 22H and further stretch spring :27, 127 or 22T. T o hold the valve in this position in spite ot' the continuing pull of spring T employv any suitable locking device such as a band brake 30, encircling pulleyv 29, on the valve spindle. One end ot this band is made fast, as at 31, and the other is connected to the core of a solenoid 32, 182, or 232. A circuit, 33, 13?) or Q33, includes the coils ot the corresponding solenoid and extends to thc sendingl station where circuits are energized bv current from any,7 suitable source of supply connected to double pole switch 36. Each circuit also includes two circuit breakers or controllers, one of each pair, as 14,

bers of the air, (35, 135 oi' 235) are located 114, or .214, being located near the valve, and branch to storage bin, while the other memat the sendlng station. l

The mode of operatioaaof the present 1nvention is substantiallfyltne same as that of 'the form describedin my Patent No.

tour, the circuit 33,133 or 233 then com- 'has leftcircuit controller 40 pleted and the solenoid energized to operate `the brakeI and hold the branch open against the pull of the valve spring. When the operator is sending from the supply station he opens circuit closer 35, 135 or 235 after 'filling any corresponding bin, thus disabling the brake and allowing the spring 27, 127 0r 227 to line.

lt anyv brake gets out of order, the spring can be disconnected and the valve operated manually in both directions by chains 15 and 2,8, etc. lf the spring goes out of action the manual operation also. may be employed, circuit controller 14, 114 or 214, being'opened to disable the brake. l

ln the drawings the valve 111 is shown in position for line, the supposition being that the operator has found that bin full, or its furnace out ofoperation, and consequently 114 or 135 open. The operator, after filling then -pull` circuit controller 35,` resetting valve l1 for line, and thus get connection straight through to valve 211, through whichhe can fill the third bin, and so on.

Other forms of valve locking and releasling mechanism could be -substitutedfor the l. .particular forms shown Without modifying v the principle involved in the invention.

Having described my invention, I claim: l
